Interventional cardiologists in the cardiac catheterisation laboratory
Who they are, what they do and which devices they use: a research-based profile for recruiting this target group for MedTech and pharma projects.
Overview
Interventional cardiologists perform diagnostic cardiac catheterisation in the cath lab, such as coronary angiography, left ventriculography and haemodynamic measurements, and decide when a myocardial biopsy is indicated. Before elective procedures they review history, medication, ECG, echocardiography and laboratory values and set the approach to anticoagulation. Radial access is their standard route, with femoral access for large-bore sheaths. They are responsible for radiation protection following the ALARA principle and use contrast medium as sparingly as possible. Their patients range from chronic to acute coronary syndrome, and selected examinations are done as outpatient procedures.

Frequently asked questions
Which examinations do they perform in the cath lab?
Coronary angiography, left ventriculography and haemodynamic measurements, plus myocardial biopsy when indicated.
Which access route is typically used?
Radial access is the standard. Femoral access is used for large-bore sheaths, and brachial access is an alternative.
What role does radiation protection play during the procedure?
Operators need specific radiation protection training and work to the ALARA principle with collimation, low-dose settings and little angulation.
What is checked before an elective procedure?
History, medication, physical examination, a recent ECG, usually an echocardiogram and routine labs such as renal function and coagulation.
Who supports them at the table?
Assistant staff from nursing, medical technical assistance, surgical and anaesthesia technical assistance, medical assistants or paramedics.
